Abstract

Material requirements for road pavement have increased along with major developments in Lampung Province. This causes the availability of aggregates to become thinner. One alternative replacement material is RAP (Reclaimed Asphalt Pavement). The aggregate in RAP becomes a potential that can be used as a basic material for road foundation layer. Therefore, research on the potential of RAP (Reclaimed Asphalt Pavement) if used as a base course material.This study uses RAP material obtained from the asphalt pavement layers on Soekarno-Hatta Street, Bandar Lampung.  The results of the maximum dry density value obtained from three behaviors amount of blow is 1.965 grams / cm3, so that the resulting CBR value is 51%. This is caused during mixing and blows, the added water cannot enter perfectly into the RAP cavity. Because RAP granules are coated with asphalt so it is impermeable. So it can be concluded that the potential RAP used in this study cannot be used in road foundation layer class A but can be used as a road fondation layer class S. And if an additional of blows are made in each layer, RAP potentially can be used as a class B road foundation material. Keywords : RAP (Reclaimed Asphalt Pavement), Base Course, Optimum Moisture Content.

Abstract

The increasing development of high-rise building construction with unique design in Indonesia today can not be denied. The high-rise buildings must have earthquake resistance because of Indonesia is a country that has the risk of an earthquake. This requires a multi-storey structure designer to be able to design a multi-storey building structure with various conditions and configurations. Based on that problems, a building will be designed with unusual shape by inclining the entire main structural column with a slope angle is 80o. And as a comparison, another building will be designed which uses vertical column. The building plan will be located in Banjarmasin, South Kalimantan, Indonesia.The building plans with inclined and vertical column use reinforced concrete material with Ordinary Moment Resisting Frame (OMRF) as a structural strength system. This system is determined by the location of the building based on Indonesian Earthquake Map 2012. The result of the analysis and design is the building with inclined column has greater internal force compared to a building with vertical column and requires a reinforcement of 70.89% more than the building with vertical column.Keywords: earthquake, inclined column, building, concrete reinforcement, vertical column

Abstract

Natural disasters often occur in hilly areas in Lampung Province, namely landslides. Landslides that occur due to increased pore water pressure. The 2012 GeoStudio SLOPE / W program can analyze slope stability that can be modeled according to the original conditions in the field and can know the value of the safe slope factor. In this study, there were three cross section slopes with three groundwater conditions, namely the condition of the groundwater level at the base of the slope, half the height of the slope and following the maximum height of the cross section of the slope. Land property data needed include : cohesion, shear angle in soil and weight of soil contents. Slope stability is achieved when the retention force is greater than the driving force. The results of the analysis of slope stability show that the condition of the groundwater is very influential on slope stability, can be seen from the results of GeoStudio SLOPE / W 2012 analysis in simulation 1 and simulation 2 safe factor values obtained >1.25 that is  slopes are in safe status, while in simulation 3 the saturated condition has a safe factor <1,25 that is unsafe slopes or landslides, it is recommended to take care to prevent landslides. Key words : soil, slope stability, safety factor, geostudio slope/w 2012

Abstract

Tanah lempung dengan plastisitas tinggi, kohesifitas yang besar berakibat fluktuasi kembang susut yang relatif besar. Hal ini yang menyebabkan kondisi jalan yang dibangun diatas tanah lempung sering kali mengalami kerusakan. Untuk mengatasi masalah tanah tersebut, dalam merencanakan bangunan teknik sipil di Indonesia memerlukan beberapa perlakuan untuk membuat tanah menjadi lebih stabil. Oleh karena itu dalam penelitian ini dilakukan perbaikan tanah dengan cara memperbaiki gradasinya yaitu mencampur lempung (tanah asli) dengan pasir (gradasi lebih besar). Sampel tanah yang digunakan pada penelitian ini berasal dari Ruas Jalan R.A.Basyid, Kecamatan Jati Agung, Lampung Selatan pada STA 3+100 dan variasi pasir yang digunakan yaitu 0, 5, 10 dan 15 % dari berat tanah. Adapun pengujian yang dilakukan pada penelitian ini adalah pengujian CBR dari efek pegembangan tanah, lalu dilakukan perhitungan tebal perkerasan dengan metode analisa komponen SKBI 2.3.26.1987. Pada penelitian inisampel tanah yang digunakan termasuk kelompok A-7-6atau jenis tanah yang buruk. Setelah penambahan variasi pasir, batas plastis tanah tersebut meningkat sedangkan batas cair dan indeks plastisitas menurun, hal ini mengakibatkan pengembangan tanah terjadi penurunan pada 15% kapur yaitu dari 0,65% menjadi 0,15%, sedangkan nilai CBR mengalami peningkatan yang signifikan pada pasir 15% yaitu dari 2,0% menjadi 25,4%. Dengan hal ini tebal lapis menjadi lebih tipis, pada 0% kapur yaitu tebal D1=7,5 cm, D2=25 cm dan D3=44 cm, sedangkan pada 15% kapur tebal D1=5 cm, D2=18 cm dan D3 tidak digunakan.Kata kunci : CBR, Pengembangan Tanah, Tebal Perkerasan, Stabilisasi, Pa
